INCANDES'CENT GAS-BURNER.

sri-:ernennen forming part of Letters Patent No. 706,686, dated August 12,1902. Application iiled December 9, 1901.` ASerial No. 85,212. (No model.)

accomplish a great saving in gas and provide a simple means of igniting, whereby any one` unaccustomed to the use of gas can light the I same with safety and prevent the explosion usually incident when lighting incandescentr burners, and consequently save the mantle from destruction; and it consists, essentially,

of a burner of the Bunsen type with a circum zo ferential slot toward its lower end in which is inserted a set-screw attached to a cap designed to regulate the supply of gas from the main pipe, a secondary burner with an opening for the ingress of gas entirely separate from the main burner, and a cut-off key provided with separate orifices designed to open and close the supply of gas to the main and secondary burners alternately, the various` parts being constructed in detail, as hereinafter more particularly described. I

Figure l is a sectional'perspective view of my device. Fig. 2 is a detail of the burner.` Fig. 3 is a detail of the nosepiece. Fig. 4 is a detail of the regulating-cap. Fig. 5 is an enlarged detail of the secondary burner.

Like letters of reference indicate correspending parts in each figure.

A is the burner.

B is the nosepiece attached to the gas-supply pipe. The nosepiece has a reduced up-V per end b threaded, and at the top of the p0rtion ZJ is the tapered portion b', which has openings b2 in its side for the escape'of the gas.

C is a cylindrical cap closed at its top end and open at thelower end and having its inner periphery threaded. The top head c of the cap has an orifice o in the center. The cap C has the arc-shaped projection c2 partially surrounding it at its lower end and attached or forming part thereof. The setscrew D is designed to iit into a correspondingly-threaded orifice ci in the'cap through the ring c2.

, The nosepiece B has an orifice E to one side ofthe reduced upper endfb, into which is inserted the tube F. The tube F isdesigned to reach up inside the burner, and at its top end is asecondaryburnerf, preferably cup-shaped andfjust protruding through an orifice ct in thecenter of the top of the main burner. The 6c secondaryburnerf has asplit screwf at the bottom and inside the bowl of the cup, which is designed to act as a regulator as to the quantity of gas allowed to pass to be consumed.

`The burner A is set on the nosepiece B and fixedly attached thereto by the screws b3, and the cap O, which is screwed on the upper yend of the nosepiece, has the orifice as in line with theQcircumferential slot a near the lower 7o end of the burner A. The mantle G is set over thetop end of the burnerfA. The gas- `key Hin the nosepiece B has .two orifices h 4and hfbored'through its diameter at positions directly under the ingress ,of` the supply for ,the `main burner and the ingress for the supply for the secondary burner, respectively.

The 4passages or orilices h and h are each diametrically direct through the key,but not par- ,all'el or onthe same plane with one another. 8o `'Ihelever I is intended `to control the key H inja limited rotatory movement each Way.

`Having described the various parts in detail,` I shall noweXplain the use of the device.

lThe various parts are attached together, as

described in the foregoing, and the main cock ofthe supply-pipe is turned on, allowing a `fullhead of gas to pass into the nosepiece B.

The passage h has been brought in line with the ingress to the main burner in turning the 9o key H by means of the lever-I.` The burner is ignited in the ordinary mannerand immediately the user turns the setlscrew D circumferentially in the groove a, so that the cap is turned up or down on the threaded upper portion b, the pointed upper end b' protrudes either more or less through the orifice o', as the case may be,thus allowing as small a quantity of gas to escape, to be consumed in the main burner as may be desired. When the user roo Wishes to `turn oif the light, he pulls one end of the lever I down, bringing in line with the gas-supply pipe the orifice h', which is also in line with the ingress to the secondary burner. This will allow a minimum quantity of gas to rise to the burner, where the outlet for the gas is controlled by the split screw f. This may be screwed down to limit materially the outflow of gas. The adjustment of the regulating devices for both burners is of course the first operation in using, and after that has been performed the turning o of the main burner will leave a tiny flame .in the bowl of the burner j'. This flame is used for igniting the main burner, as the instant the lever I is -turned and the Vpassage h opened the said flame lights the burner A at the very bottom of the mantle Gand is at once turned off itself by the closing of the passage 71,.

It will be seen that the main burner and the secondary burner are never burning for more than an instant at the same time, as the moment one is ignited the supply of gas for the other is cut od.

The importance of having regulating devices for both burners can hardly be overestimated, for as Well as I am aware the combining of regulating devices with a burner of the type described has heretofore been unknown.

The ease with which a child may operate my device ,is an important factor in my burner.

s There is absolutely no danger to the user, as

the lighting and extinguishing are practically automatic. The ignition of the gas at the bottom of the mantle materially saves its destruction, as there is no explosion, so common to all incandescent burners. The danger of constantly using matches or vestas is to a large extent avoided, and the quantity of gas consumed by the secondary burner hardly exceeds the ordinary leakage from the meter. Therefore in the matter of expense I have reduced such a convenience to a minimum.

What I claim as my invention is- 1. The combination with the mantle-sup` porting double-cylinder burner having openings in the outer wall thereof, of a secondary burner substantially cup-shaped in form and extending up within the main burner, a pipe extending down through the cylinder-burner and connecting bya passage-way to the main gas-supply, the said pipe having extending into the upper end thereof, within the cup, a slotted set-screw capable of being turned from the top as specified.

2. The combination with the mantle-supporting double cylinder having openings in the outer wall thereof, of a nosepiece having' a central orifice and fitted onto the upper end of the gas-supply pipe and receiving the lower end of the outer wall of the cylinder-burner and having a reduced threaded upper end suitably tapered and flattened at the top and provided with an opening therein, a cylindrical cap internally threaded and provided with a central opening at the top designed to t over the reduced upper end of the nosepiece and means for circumferentially adjusting such cap and holding it in position when adjusted as specified.

3. The combination with the mantle-supporting double-,cylinder burner having openings in the outer Wall thereof, and a circumferential slot formed at the lower end thereof, of a nosepiece fitting the central orifice, and fitted onto the upper end of the gas-supply pipe and receiving the lower end of the outer wall of the cylinder and having a reduced threaded upper end suitably tapered and flattened at the top and provided with an opening therein, a cylindrical cap internally threaded and provided with a central opening at 'the top designed to fit over the reduced upper end of the nosepiece, and an arc-shaped projection formed on the cap and fitting the interior of the lower portion of the cylinder, and a set-screw extending into the arc-shaped projection and through the slot as specified'.

4. The combination with the mantle-supporting cylinder-burner having openings in the outer wall thereof, of a nosepiece having a central orifice and fitted onto the upper end of the gas-supply pipe and having the top tapered and an openingextendingtherethrough, a cap provided with acentral opening suitably fitted onto the nosepiece, means for adjusting said cap,a side passage-way extending through the nosepiece to the gas-supply, a tap having the central orifice designed to communicate with the central orifice of the nosepiece, and a side orifice at right angles to the central orifice of the tap and designed to communicate with the side passage-Way, a pipe extending up-Y wardly from the side passage-Way in the nosepiece and bent at the top so as to have the top centrally disposed and a suitable burner at the top, as and for the purpose specified.
